Is my Saikano 650 enough?

post #1 of 16
Thread Starter 
Godd night people.
I have the system described in my firm and i'm thinking of upgrading to a GTX 580 Lightning, sould my Saikano 650w be enough?
Extra data i'm planning to do some OC to the card.

Thanks For the answer.

EDIT: I search in the forum. But there is no concrete info about my PSU will hold or not.

You're really stretching it... and forget about SLI. I would go with at least an 850w PSU, maybe 1000w for upgradability. If it's a really quality unit, it might be able to put out 800w max, but that would be a huge strain.

And this is OCN, don't be afraid to overkill

With an overclock on the GPU, you might reach just a little bit above 500W in full prime95 + FurMark type stress testing, but well under 400W for peak power consumption in a game. An okay-quality 650W would be plenty, so most likely you're okay even in the worst case scenario.

I've never head of the Saikano Eco though, but that doesn't necessarily mean it's bad, just that it's a regional brand for which we don't see many reviews. Anybody know the OEM/platform and if it's any good?

I've never heard of the Saikano Eco PSU before, but I do like the anime series Saikano (shortened version of name).

Thanks for answering. Saikano is regional brand. On the side of the PSU i read that the 12v rail delivers up to 49 amp. Also claims to have "real" 650w with a max of 710.
I don't knows if this values are true.

That is why i created this thread. In my country (Argentina). High end PC components are rare and expensive. I was looking to buy a xfx 850 black edition but here cost nearly 252 dollars, plus the 580 lightning, another 850 are more than 1100 dollars. That is two months salary.

So i want to know if is really neccesary to buy another PSU.

Sorry for my english and again thanks for the answers.

Saikano units are from the OEM ATNG.

The platform is the APL/APG and it's pretty good. Your unit should hold up and be fine.

Though the Saikano FPS 1000w I would hold with caution (I'm assuming you got it because it was an affordable brand and you would consider them again) as the ATNG platform used is the Modular 87+ from ATNG which is known to have excessive ripple and lack luster Voltage Regulation above 900w.

Either way, the unit should be fine as it's a reliable platform.

Rosewill uses it in their Green Series 630w and Performance Power 650w.
The Saikano Eco 650w looks to be the same as the Performance Power 650w which has the downsides of tight protections (above 40*C it'll shut down due to OTP) and it's efficiency isn't all that good for a modern unit.
The capacitors are a bit on the "so-so" side, but they are 105*C Teapo's which are not bad and usually don't present an issue.

Thanks tator tot. Very well explained.
i bought that psu when i didnt know anything about psu. I'm upgrading but i can't afford two thing right now. so i preferto buy the 580 first and then the psu.
I was thinking about a xfx 850 black edition or a hx 850.

what do you think?
post #9 of 16
You don't need a PSU of that size at all. Stick to 550w-600w units if you're looking for a single card setup. Even an HD6990 would be fine with a solid 600w unit.

That is what i read. But not knowing the quality of my PSU. I can't be sure.
Extra data. Before this rig I had a:
Q9400 @ 3.4
Ram 4GB
500 Gb HDD
Ati Sapphire 5850 OC at 950 / 1150(same as now)
and a XFX 9400GTX 512(Phisx) Also OC.

Rep for you Tator Tot. It seems that you are the only one to give some advice.

Thanks.
I don't know if a 2600k Consume more that a C2Q. What do you thing.
