Hi

Will a HiPER 425watt PSU be enough for..?

1 Intel E7200 Dual Core CPU
1 nVidia 8800GT
2 x 1Gb RAM
1 x Hard-drive
1 x DVD drive
1 x Motherboard
425w PSU HiPER

?

Ive already built the same but with E4500 Dual-Core and 8600GT and its been fine 6 months on just wanna be sure before I build it for my Dad - does the 8800GT require its own power lead from the PSU?

NO on two counts. First, the Hiper is one of the weakest power supplies on the market IMHO. Second, with that video card, you need at least a 650 watt power supply in that rig. Here are great brand name power supplies:


Seasonic – Any Model
Corsair – Any Model
PC Power & Cooling – Any Model
Thermaltake – “Toughpower” Series Only
Coolermaster – “Real Power Pro” Series Only
Silverstone – Any Model

650 WATTS!!! how come my build with the 8600GT works just fine with the HiPER 425w ?
just 1 DVD drive and 1 Hard drive and intel E4500 2.2Ghz..??

Ive used its heavily with games for hours before handing it over 6 months ago to my uncle who uses it for web and autocad

I though for SAME build but a 8800GT instead of 8600GT it would be good enough?

An 8800 uses more power than an 8600 and is a much better card. In addition, while you might get by with a good brand name (see the list) 550 watt with that card, it is always wise to have a little in reserve in case you get itchy in a couple of months and want to add something new. If you just get the basic, then if you want to add, then you have to do it over again at that time. The few extra bucks are well worth doing it right the first time around.

This is YOUR choice, but you asked for an opinion from a tech, and that is mine. I would not purchase less than a 650 if it were my choice with this particular video card which is a power hungry animal (a great card though at that). BTW, if you look at NewEgg, you can find some excellent buys for the 650 that are as reasonably priced as some of the 550 watt units.

Hi, Paul
Recently, I had to fix a similar spec system to the one you are building, except it used an 8600GTS OC'd. The Hiper 425W was giving irregular voltages so I replaced it with an OCZ 600W and all was fine.
The 8800GT is a much superior card to the 8600GTS and demands much more power. Like the guys have already said, look for deals on a 650W+ from a good brand.

The advice given on the link below is the MINIMUM requirements......

thanks guys

thats fine

(that link says 400w - 450w for 8800GTS or 8800GTX on a system with Core2Extreme) ???

the reason for the 425w on the 8600GT build was cos my uncle didnt want to spend money and wanted it as cheap as possible - he wouldnt even replace the 80GB HD he had so i had one IDE port serving both DVD and HD - i told him the complications of future upgrades but i doubt there will be any except replacing the IDE hard-drive with a SATA one... he is tight fisted so...

just to be sure: the 425w HiPER wil be OK for my uncles system (8600GT+E4500) thats been fine for 6 months now and was fine under heavy load from me for hours/days when i built it? he not a proper gamer he just wanted for SIMS (kid) and AutoCAD and Age Of Empires etc... if in the future he wants to upgrade the Cfx card I will say "you will also have to upgrade the PSU cos u wanted to keep it cheap thats best I could do..." but I very much doubt he will want to upgrade -

BUT ive ordered one for a build im doing at mo' this DOESNT have a Gfx card and is a budget tower for £148 - 2Ghz Dual-Core Celeron with 1Gb Ram and XP and 80Gb HD and DVD-RW - so its gunna be fine for that defo... ...but for my Dads upgrade he needs 600watts - im surprised at the power he needs to go from his current P4 with 300watts to 600/650watts JUST cos of a graphics card???

he has an Acer Aspire SA80 / LGA-775 P4 3Ghz HTT / 1Gb Ram / XP / DVD-RW / 160Gb SATA HD ...

now on my other thread ive explained that were gunna tear its guts out and stick in all new parts (apart from HD + DVD for now - those later) - he fancys the E7200 and 8800GT , but this is MONTHS away and ive said to get my uncles old AGP 6200GS to stick in current setup which will play Flight Sim X no probs until he gets 'beefed up'

thanks guys

Hi again Paul,
The important part of the nVidia advice on power supply for the 8800 Series is not the Wattage, but the Amperage.

You'll see the 8800GTX needs 30A at +12V and the GTS (which is practically the same as the GT) needs 26A.
You must also remember that this is "at least" 30A & 26A.

All the techies I know recommend at least 26A on the +12V Rail, just for entry-level PCIe cards.

This is worth reading........
http://www.techsupportforum.com/f210...on-192217.html

If your Uncles PC is working fine, then leave it. Like every other electrical component, sometimes you get good ones, other times they are ok and sometimes crap.

thanks for that

it was sum1 one TechGuy Forums that 'verified' my uncles build would be fine I remember him saying the specs or rails (or whatever the words are) looked fine... - im not really a gamer and had never dealt with gfx cards etc so now im starting to get into it so I know for future (like my dads)

thanks for that link youve been very helpfull :) and will read it ASAP

we will always advise you of specs that will never get you in trouble .....a power supply loses 10-15% of its capability each year from capicator aging ? did you know that

and when a cheap power supply dies ..... it has the habit of killing the motherboard, ram or hard drives ..... that doesnt happen to systems when we advise parts !

I can see squeezing the lemon on a cheap build using a low end ..... not demanding video card; like the 8600 but when you pay good money for the 8800GT, its time to step up! you cant run a race car on cheap tires and you power a high performance video card with a marginal power supply ...... BTW: yes the 8800GT needs its own power connector coming from the PSU

as for power ........ I would never run a P4- 3.0 ghz machine on anything less than a 500 watt power supply either ........ just remember when you learn your lesson the hard way ..... you provoked Murphy's Law


look here :

http://www.slizone.com/object/slizone_build_psu.html

an 8800GT uses about 100 watts give or take a pinch ........... look at the units NVIDIA advises you to use then substract 100 watts from their reccomendations

goodluck

Lets put it this way.

I have a 9800 GTX.

One of my friends has a high-amperage meter.

In peak game (about 50 cars on track at lemans in GTR2 @ 35 FPS and 65C), we recorded about 30 amps flowing through just on the gfx line alone. For those wondering how I metered this, I was able to work one of the wires out of the 6 pin adapter, electrical taped the wire to the tester lead, and put the other lead in the 6 pin connector. 5 +-0.5 amps on one single wire...there's 6 12 volt wires going to the gfx. Assuming it puls an equal amount for each 12V wire, thats 30 amps.
