Just read the huge wall of text about selecting PSUs etc..

Just abit curious if these PSU(s) would be deemed "Good" or "Decent"...
I made a thread about a week ago buy that thread died.


I currently own a DPS-220UB, Which is 220W, I'm need to upgrade to something ATLEAST OVER 500Ws and under $70USD if possible
( P/s I'm from New Zealand)

EDIT: Here are my specs if needed.


At first I was just going to buy a $32 USD 500W PSU, but after reading the Sticky regarding selecting PSUs I would rather spend more money to get a better deal.

I need a minimum of 450W to run my new GPU, but accoring to your thread it says get 30% more than the what it says. Therefore I'm wanting to get another 100Ws just to be way out in the clear.

P/s Is there anything special I should look for when choosing, I've noticed that the PSU I have know has very few plugs ( What looks to be.. 1x20Ping, 4x 4Pings (One of which is not plugged into anything))

All the other ATX PSU's I've looked at seem to have 8-9-10 cords. Does it matter if there are cords just lying around? (Stupid question considering I've got one lying around in my current case)


Depending on how I get on I will post more PSUs.

Thank you in advance.

neither of those power supplies are good they are both generic crap.

Seasonic,corsair,xfx,cwt,thermaltake (toughpower only), bequiet, ocz extreme are good with the first 3 being the best.

Power supplies are important and good ones are needed if you value your system.

I'm sorry for continuing to post on this topic changing the question etc but...

What actual effects will I be putting on my computer from using a "poor quality" PSU..
I mean, I've been running of a Delta Electronics PSU which before I pulled open the box I had never heard of fine, why should another PSU be any different?

Yes I've read your stick regarding selecting a PSU (twice..)

I'm sorry if I seem like an idiot to you right now but yeah...

Thanks,

Your luck the delta hasn't caused you problems.

Often with low quality power supplies the manufacturer is a bit too generous with the power supplies actual wattage and this can cause people to buy a psu that they think is good enough for their system when infact it isn't and it will eventually cause hardware damage.

The psu is the heart of your system and should be a good quality unit to stop bad things from happening. Think of it this way you have a sports car and need to put petrol in it. You cant just put any old petrol in it you need to use high octan petrol to stop the engine from getting damaged.

The same goes for a psu if you use a low quality one then the conversion from ac electricity to dc electricity can go wrong and if any ac electricity gets to your components then they will fail. The capacitors in good quality units can take a lot of pounding from the system and handle electricity spikes, and blackouts where as low quality units can't.

I have seen power supplies like your delta rated at 800w but when they were tested properly their real rating was 600w
