Hi all!
As this is my first post here, let me congratulate You on this great forum! You really rock!
I need to buy a home UPS as my little village power line is every day worse and worse, with continuous blackouts especially after 2 drops of rain!
I have already lost a PC because of that And I have learnt that buying a good PSU can help it very much, so my actual PC is powered by an Enermax Liberty 400W.
Anyway now that such blackouts are more frequent I do not feel safe anymore, and I decided to buy a UPC.
I am only a student so I can't afford spending much more than 150€ ( I live in Italy - Power Line 230V, 50Hz)..
After reading this:
Of PSU, UPS, PFC and Sine wave
I feel really hopeless, having my PSU Active-PFC.. and being Pure Sine wave UPS so expensive

I found the following (not Pure sine wave) for prices that I can afford:
MICRODOWELL B-BOX XP150 1500VA (175€) - Can I trust this brand?
APC BACK UPS RS 800 Va 540 WATT (160€)

And this is my rig:

PSU: Enermax Liberty 400
CPU: Pentium D 3.20GHz (cooled by freezer 7 pro)
Motherboard: P5WD2
Video card: NVIDIA GForce GTS 250
HDisk: 2 HDisk Maxtor 250GB SATA2
Monitor: Sony Multiscan 200ES (CRT)
DVD: Pioneer DVD-RW DVR-116D
ADSL: via ethernet
Cooling: 3x 12'' Enermax magnetic spin

Moreover I would be very glad of being able to reuse the UPS for a new rig as soon as I can afford it..

Thank You very much in advance for any suggestion!
Stefano B.
