Will this PSU be enough for my new rig?

NebachadnezzaR · Oct 10, 2014

Hi. I'm finally thinking about upgrading my 5 year old rig and I'm afraid that my psu won't handle it.

It's a Tacens Radix V 850 which, from what I've gathered here in the forums, it's not very good (it wasn't my original choice, my first psu died and the guys from the repair shop chose this one to replace it).

I still haven't fully decided what my new cpu+gpu will be (along with the motherboard and more ram, they're the only components I'm planning to buy) but I'll probably either go with an amd FX 8350+R9 280x, or an intel i5 4430+gtx 970. While I will appreciate some comments on these choices, I'm posting them merely so that you understand the load that will be on the psu.

That being said, can it handle it? I really, really, don't want to spend any more money than I have to, I'm alread stretching my budget thin ant a new psu would just kill it.

A new PSU, sadly, is required. That's a very poor quality PSU and being 5 year old, the caps will be worn out, you wouldn't want the PSU to explode, taking some components with it, for a high end build like that, straight no. And i5 + 970 would kill a single 280X and FX 8 in gaming.

Can you not save another month longer for a decent PSU? I mean it's 850w so it should be able to handle most mid range GPU+CPU combo's but i just cant be sure. Personally i wouldnt risk it having a fault and causing further issues down the line (maybe even damage to your new parts).

Thanks for the answers. Can you suggest a good replacement? As I've said, money is an issue, so I'll be looking for a great quality/price ratio.

This PSU has a great value/money ratio, while being decent quality and fine wattage:

Power Supply: XFX 550W 80+ Bronze Certified ATX Power Supply ($44.99 @ NCIX US)

Any 550W or higher PSU from Antec/ EVGA/ SeaSonic/ XFX would do.

here's quite a detailed post regarding what branding of power supply to buy: http://www.tomshardware.co.uk/forum/323296-28-best-brands

I'd suggest a 500-550W PSU, bronze rated or higher. If you want to overclock or SLI it in the future then you'd have to go for a higher wattage PSU

Edit: never mind, MeteorsRaining covered it! what he said

NebachadnezzaR · Oct 10, 2014

I probably won't be overclocking nor using sli/crossfire, so is more than 550w overkill?

I just searched for the psu MeteorsRaining suggested and in my country it sells for less than 60€, which is awesome! If you guys think this one will do, I'll go with it. Thank you both so much for your input.

MeteorsRaining · Oct 10, 2014

More than 550W will not be overkill, just unrequired, actually we can say more than 650W will be overkill. And yes that PSU is a great value/money, wise decision there. Glad to help
