Yet another: "What PSU should i get?!?!11!" :)

post #1 of 22
Thread Starter 
Hey. Ive got a generic 350W psu at the moment, but I plan to get a 7800GT in the near future, and i dont think it'll hold up.

Basically, I want a PSU that will provide enough power for HD, DVD-RW, MOBO, possibly 2 7800GT's (will upgrade to SLI in future) and 4 fans (80mm). I dont have a floppy. But that shouldnt matter too much anyway . What wattage am i aiming for - 450/500?

I dont want the best (and most expensive) PSU around, but i want one with good enough quality to OC (better than my current OC, but thats to do with cheap memory anyway).

Oh, I've got an ATX mobo.
Its got a 24 pin socket, but at the moment its running off a 20 pin PSU. Is that bad?

Here's your best bargain....
http://xoxide.com/sunbeam-nuuo-550w-psu-black.html It'll power your entire system and is more than enough for OCing.

OCZ Powerstream 520. SLI ready, rock solid & adjustable rails. As a previous owner I still can't do it enough justice... it was absolutely awesome.

Nice, comes with a fan controller too

I'll have to look for it in the UK though. Are PSU's generally the same price across the atlantic?? Because thats roughly £50 over here, and thats much less than i expected

This (US site but the product info is relevant) is my favorite PSU on the market for the price. I've been extremely happy with mine. It handles my 24/7 folding on my heavily OCed rig while gaming. It's also SLI certified and all of that good stuff.

So it would seem OCZ or antec are the brands to go for. I should look for a PSU between 500 and 550w right?

That sunbeam one - i cant find a single place in the uk that sells it

If you can fit the Seasonic 600W into your budget, there's no reason to keep looking It finishes in the top of every review I've seen and it's quiet and efficient. It sells for $135 US, not sure what it'd be overseas.

Edit: here ya go, 75 for you guys on a 1 week sale

Your pricing seems to vary widely...

Hmmmm. I was looking to spend no more than 80 pounds. OCZ are very expensive compared to others, but i know this does reflect in quality. Antec seem slightly cheaper, and they don't have crappy gimicks like glow in the dark cables - they just add more to the price.

I mean take this for example: 680W thermaltake

compared to a 450W OCZ

Prices do vary alot, people (like me :S) don't know what to buy so they blindly buy the most expensive and overpriced by the shop. I've known people that only use there PC for work that have a 550w PSU

Oh, btw, will I be alright with a 500W?

The amperage is as if not more important than the Wattage. Anything in the 450+ Watt range is probably fine, though getting over 500 W is certainly a good thing. Look for amperages on the 12 volt rail in excess of 30 amps with something in the high 30s or above being very favorable (especially if you go SLI).

You're absolutely right about the gimmicky stuff. Money invested in a high quality PSU (Antec, OCZ, PCP&C, Seasonic, and others) is money well spent as each and every component in your system will benefit from a good PSU.

Thanks
Never thought about amperage.

In general, whats a "quiet" PSU? I know it works logarithmically. If its below 20 dba, is that quiet?

I dont mean it like insultingly to all those who have really pretty PSU's, buy i havnt really modded my case, so I'd rather just get a practical ugly PSU than one thats coverd in LED's

Oh, and why is this so cheap compared to others? is there anything wrong/avoidable with it? Antec 550W
