Will my OEM Psu will be enough to run one 5770 (XFX) + rig?

Heres the link to product.

Its a little different but heres spec
Continue power: 400W
12V1 = 16A
V2 = 17A
Cant exceed 300W

Safely: no

will probably blow up when you load the system: yes

 

[Phaedrus2129]

Not really.

Yes, it can deliver its rated wattage, but it has a +12V rating of only 250W which makes this in real use a 300W PSU at best. Technically it's enough for your system, but I get the impression this is an old ATX 1.3 design, so running a +12V-heavy system like yours on it will likely cause crossloading, and possible instability.

The Corsair CX400 is $30 after rebates at Newegg right now, best bang for the buck on a quality power supply. Get it.

I'd have to say no as well....and listen to Phaedrus,he's one of the resident psu experts.

What's the cheapest but have quality PSU? Looking to get a GPU and PSU

You won't be able to run it safely.
The Delta is a fine PSU, but its older design and the fact that its an OEM means its not heavy on the 12V, as per the specs you posted.
Get a better PSU like Phaedrus mentioned.

When looking at a psu don't focus on cheap, focus on quality. Look at the corsairs for your best bang for the buck and performance and reliability. JMO

yeah dude i just got the corsair CX400W PSU and alot of people said its great.

edit: wanted to start new topic, not post here.. sorry

 

[Eagle1337]

the antec basiq's are too bad either, The SeaSonic SS-350ET, although with the seasonic you get an ugly gray case.

 

[SinX7]

Well casing don't really matter right now, I just got a basic ASUS OEM case (I got a ASUS OEM computer)

Edit:
Which of this will be enough to power rig + gpu + OC?

I might get the OCZ tho.

 

[newbile]

how much are you trying to spend OP?

 

[letsgetiton]

This one will be fine of the ones you listed. $70 w/rebate.
This is what I've been using for the last 2 years. $50 on sale.

why spend more when he doesn't need a 650w psu? a Seasonic SS-400ET is like 40$

 

[xquisit]

What happens when you want to run crossfire? I think a new PSU will be best, and no need for paranoia.

He "needs" at least a 500w PSU. That card recommends a 450w PSU and that extra 50w isn't much. You don't want to run your PSU at full output. A 80% rating means the 500w PSU will put out 500w up to 80% usage, then drops off quickly after that due to heat. So even with a 500w PSU, if you go near or past 80% you won't be even getting the 500w. That's why you always buy a bigger PSU then you need. (hence the 650w) A 650w PSU won't get near 80% usage therefore always giving you 650w full watts, not to mention run much cooler and quieter.

You don't understand power supplies at all... A proper 500w psu can do 500w, not 80% of 500w. Efficiency will drop yes but it will do 500W fine and won't suddenly go kablewy.

a c2d with a 5870 uses about 380 watts on load....

 

[computeruler]

Uhh no. A good power supply can do the rated wattage, and sometimes more, with lower than rated efficiency of course.

 

[SinX7]

I dont have room for Crossfire. My range is around $60 for PSU since i want to get a 5770.

 

[KRAZYTRUCKER]

Make sure and focus on 12 rail amps and not so much on watts. This seems to be missed alot when deciding on psu
