Default Could you suggest me a good PSU with Passive PFC?

Hello everybody, please, excuse me for my english!

I need to buy a new PSU for a machine wich won't need much power, but it will be used with a UPS wich don't support Active PFC.

Question is simple: are there any very good PSU (in term of brand, components quality, stability and durability) with Passive PFC? I don't need much power, i'm looking to 450W/550W range. The main concern is to assure the longest live possible to PC components.

Thank you in advance.

In Win IP-S400CQ2-0. It lacks PFC and is reasonably well built. Similar story with some Antec VP models.

Thanks for your reply.

I found an Antec VP450P for sale in my country, but i'm a bit confused... the review on HardwareSecrets says it has Passive PFC, the specs page on Antec website, instead, claims it has Active PFC...

Who's right?

I don't think Hardware secrets have reviewed the VP450P, only the VP450. The VP450 lacks PFC, while the VP540P has APFC.

...oops, maybe i made confusion with another website

Anyway, the In Win PSU is unavailable here in Europe and i'm afraid the only version of Antec VP450 i can find here is the one with APFC

Practically EVERY PSU sold for under 30 here is with Passive PFC, but they are from unknown or cheap brands... and i need a GOOD one

Get another UPS then. If it doesn't work with APFC, then it's probably just as low quality as a $30 PSU

I bought the UPS, not for "quality", but to have time for saving and shutdown in case of blackout, and it performs its job very well, giving me up to 10 minutes autonomy and alerting everybody with a very loud sound.

I know i can't have both things together (keep this UPS and have a great PSU) but i still can't resign to take a cheap unknown or no brand product

...there must be a "middle ground"...
