selecting a PSU

**okeee** · 06-03-2009, 11:00 AM

I have to select a new PSU. What do I need to consider, except the amount of Watt? Any reliable brands, and what brands to avoid?

Give us your complete specs including the video card.

**okeee** · 06-08-2009, 11:17 AM

2 PSU:

PSU1: 650 Watt, Output +3.3V@24A,+5V@30A,+12V@52A,-12V@0.8A,
+5VSB@3.0A

PSU2: 525 Watt, Output +3.3V@24A,+5V@24A,+12V1@25A,+12V2@25A,
+12V3@25A, -12V@0.6A,+5VSB@3.0A

Which one is better?

What are the Brand(s) of the two you have listed?
What are your needs?

I'll check on the brands, but can you tell from the specs which one is better?

**Tyree** · 06-08-2009, 02:35 PM

The 525W has a lot more amperage on the +12V rails but that is useless if the PSU is not a quality unit and if it is not enough overall power for the intended PC.
No one can give you any factual info without knowing the PC specs.

**okeee** · 06-08-2009, 02:54 PM

PSU1: CORSAIR CMPSU-650TX 650W
PSU2: ENERMAX PRO82+ EPR525AWT 525W

it's for a gaming pc, videocard will probably be en9800gtx+ or engtx260.

**wrench97** · 06-08-2009, 03:54 PM

Strange specs on the enermax the amps add up to more the the total output.
Go with the corsair.

**okeee** · 06-16-2009, 04:03 AM

I asked a shop for a PSU, I aked for CORSAIR CMPSU-650TX 650W, they didn't have it and recommended Cooler Master Real Power M620 Modular.
Is this as good quality PSU? I can't find much reviews about it.

Tumbleweed36 · 06-16-2009, 04:36 AM

The Real Power IS NOT the same quality as the Corsair. I would try another shop to see if you can pick one up.

**okeee** · 06-29-2009, 10:33 AM

-I've checked the PSU cables to connect to all the hardware, and there are lots 4 pin (horizontal) black and white cables. Does it matter which hardware connect with what cable (color as well) or will any that fits be ok?

-When all hardware is connected, there are so many wires that keep touching some of the hardware. Is there any hardware that NEVER should be touched by the wires?

-About static electricity, I've read that it's sufficient to touch the metal case to prevent static electricity. Does it matter where the case itself is placed, for example on a wooden table?

**wrench97** · 06-29-2009, 12:53 PM

The 4 pin will be for IDE drives or fans that's all there used for today.

Just tie and roll the wires into a loop and store excess in an unused drive bay, about the only thing to avoid wires touching are the heat sinks and fans.

If you touch the case then you and the case have the same charge so no discharge will occur.

**okeee** · 06-29-2009, 02:10 PM

The 2 fans from this case:

are they both outtake fans? So that I have to put in at least 1 other intake fan?

**simpswr** · 06-29-2009, 02:37 PM

Fans in the front and side should blow into the case . . . fans on the rear and top, should blow out. That case also has one on the top that blows out of the case.

That is a nice case . . has room for the extra wires on the side of the optical drive cage. It also has room for a third fan in the front, to blow air aacross the hard drives.

**okeee** · 06-29-2009, 04:21 PM

There are 2 spots for extra fans on the front panel, but would 1 be sufficient for heavy games?

**simpswr** · 06-29-2009, 04:29 PM

One is all I have done . . locate it so that the drive gets the most circulation

**wrench97** · 06-29-2009, 04:40 PM

One fan in the front is fine, just enough to move air across the drives.

**okeee** · 06-30-2009, 12:43 PM

I'm interested in this case: Antec Three Hundred but I would like to know a certain length inside the case, which is the length between the rear panel and the front panel, the length where the videocard should be placed. Does anyone have such a case and please measure it? Length in cm would be ok.
